CAN-SOLDERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 443,289, dated December 23, 1890.

Application filed June 11, 1890. Serial No. 355,001. (No model.)

To ctZl whom it may concern.-

Be it known that I, GEORGE E. LOOKWOOD,

. a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Can-Capping Machines, which improvement is fully set forth in the following specification and accompanying drawings.

Our invention relates to improvements in can-capping machines; and it consists, first,

of mechanism, substantially as described, for

' tially as described; sixth, of the combination of parts herein described.

Figure 1 represents a sectional elevation of a portion of the machine, showing a section of the frame with driving-shaft and cappingirons and mechanism for operating the latter. Fig. 2 represents a sectional View in elevation of the same parts at a right angle to the view shown in Fig. 1 at a different stage of the operation. Fig. 3 represents an end view showing the solder and the acid feeding devices. Fig. 4 represents a view of the parts shown in Fig. 3 at right angles to that shown in the said figure. Figs. 5 and 6 represent detail sectional views of a capping-iron and side views of a weighted tip-rod atdifferent times of operation. Fig. 7 represents a sectional view, on an enlarged scale, of the valve mechanism of the acid-tank, the dotted lines on the left showing the plunger-head enlarged. Figs. 8, 9, and 10 represent horizontal sections of the capping-iron-operating mechanism on lines a: as, y y, and z z, respectively, Fig. 1, on an enlarged scale. Fig. 11 represents a perspective view of the universal-joint attachment for the capping-irons. Fig. 12 represents a sectional view of the periphery of the grooved cam-pulley for operating the capping-iron mechanism. Fig. 13 represents an end view of the machine cmbodyiug the invention.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates the frame of the machine, having abed portion 13, 5 5

ble portion and sections having rollers thereon on which the trays move.

Journaled in the lower portion of the frame is a driving-shaft E, which receives rotary motion from a suitable motor by means of a band-pulley F.

The trays O are provided with projecting pieces G, affording bearings for operatinglevers.

On the shaft E is a cam H, adapted to come in contact with and oscillate a lever J, pivoted at its lower end to the frame A, and having pivoted thereon at different distances from its pivotal connection with the frame two balanced' levers K L, each of which has hooked ends adapted to engage the projections G of the trays, so as to advance the same on the table. It will be seen that the hooked ends of the levers K L travel different distances during each movement of the lever J thereby permitting the longer lever, which moves the greatest distance, to engage the first projection of each tray, thus allowing for the thickness of the two walls at the ends of the two trays between the cams, the other lever, however, aiding in the movement by engaging the last projection of the preceding tray near the end of the movement, so as to prevent a jarring of the trays.

M designates the capping-irons, which in the machine shown in the drawings are four in number, but which may be six or more, if desired. Each of these irons has a universaljoint connectign N wit-h a hollow spindlel which is provided at or near its upper end with a collar Q, which bears upon a yoke R, 5

carried by the hollow tube or pipe S; The said pipe S is supported by means of an adjustable collar T, which is secured thereon on the pivoted lever U, so as to be raised or lowered by the oscillation of the same. The spindles P move in the vertical sleeves V, which are secured to the projection of the frame A. To raise and lower the said lever U, a rising and falling red X is provided, having its upper end in contact with said lever U, and its lowerend provided with a roller which rides on a cam Y on the shaft E. A guidetube Z, secured to the frame A, incloses a portion of the red X. lVithin the spindles are the weighted tip-irons A, each having a flaring serrated lower end to securely hold the cap in place during the soldering and cooling.

To give a partial rotary oscillating motion to the capping-irons, the portion of each of the spindles P within an upper recessed portion of the sleeve V is provided with a pinion Y adapted to be engaged by a sliding rack 13, which enters at one side of said recessed portion, the rack being of such width that the pinion in its rising and falling movements with the spindle is always meshed thercwitl1,so that the spindle will at all times be actuated by the motions of said rack. The rack is pivotally connected with an arm 0, which is pivotally connected with a lever D, having its lower end working in a slot or recess E, shaped as shown, (see Figs. 1 and 12,) of awheel F on the shaft E, the rotation of the pulley thus causing the reciprocating movements of the racks l3, and thereby the oscillations of the spindles 1 with their capping-irons. The shape of the slot E determines the movcments of the racks.

Journaled on an attachment of the frame A is a shaft G, having a ratchet-wheel H loosely mounted thereon and secured to the loose member J of a clutch mechanism. 011 the said shaft are secured the wheels L, having their peripheries concave and knurled, forming passage-ways for the wire solder, which is drawn from the rotatable spools M on spindles 011 the side frame N and fed through the guides P P and pipes Q to the capping-irons. The pivoted ten sion-levers R B have in their lower ends rollers adapted to bear against the wire and are connected at their upper ends by the spring S.

To stop the operation or feeding of the wire solder when a tray is not beneath the capping-iron, so that the wire will not be wasted, the following-described shifting mechanism for the said purpose is employed: A shaft T, suitably journaled in the frame A, carries at one end a weighted arm 'LT, having one of its ends held down by a tray when the same is beneath the capping-iron, so as to hold in position a bent arm V, which is on the said shaft, and adapted to laterally move the fast member V of the clutch into engagement with the loose member and the ratchet-wheel ll, and thereby cause a revolution of the wheels L, and thus a feeding of the wire solder. When the tray is removed from the end of the arm U, so that said end is not held down thereby, the weighted end causes the shaft T to partially rotate, causing the bent arm U to release the fast member W of the clutch from the loose member thereof, so that the ratchet-wheel If is free to revolve on the shaft T without rotating the latter, and thereby the wheels L, and causing the wire solder to be drawn from the spools. The ratchctwheel is operated by a pawl Q connected with the rising and falling rod R which is operated by the cam R on the shaft E.

To cleanse the top of the can and cap, so that the solder will readily flow thereon, as well as adhere thereto, a bath of solder, flux, or any suitable acid-sueh as muriatic and zincis spread upon the surface of the same by the oscillating brushes X X, which are secured to the oscillating arms Y Y, attached at their inner ends to the collar Z on the tube or pipe S.

The supply-tank A is suitably supported on an attachment of the upper part of the frame A and provided with downward-projecting outlet-pipes 13 JP, leading from the upper part of a chamber 0 of the tank, the said chambercommunicating at its lower end with the main portion of the tank. The acid is raised from the said chamber bya plunger D which has the openings D in its head, through which the acid passes, and around the upper edges of said openings are flanges, between which and the walls of the chamber (3 a portion of the acid raised or lifted by the upward movement of the plunger is kept from flowing back through the openings D until it can escape by the discharge-outlets 13 and thence into the hollow handles of the brushes X, and thus upon the bristles or wiping portion of each brush. The upper portion of each handle has a funnel-shaped attachment 1 secured thereto, which catches any drip of the discharge-pipe when the hollow handles of the brushes are inclined and not in line with the lower ends of the outlet-tubes. The plu nger D is operated by means of the rod F which is connected by the arm ll with the plunger, and has on its lower end an arm ll", adapted to ride upon the cam G2 on the shaft E.

The lower end of the central tube S is provided with burners W in close proximity to the capping-irons, so as to readily heat the same, and its upper end is connected by any flexible hose with a gas-supply, so that it may serve notonly as a support for the cappingirons, but as a heater for the same.

J designates a pipe, which is secured to the frame of the machine and leads from a coldblast; supply to the vicinity of the cap nngirons, so as to direct a cold blast on the top of the cans when the capping-irons are raised therefrom. The said pipe is provided with a valve K, which is opened and closed by a lever L connected therewith and having its lower end adapted to ride on a cam 31* of the wheel F.

The operation of the machine is as follows: The trays C,with the cans thercon,arc placed on the tables 13 and-the caps placed thereon. The shaft E is rotated and, owing to the cam II and the spring N the lever J is moved, so that the levers K and L are placed in such position that the lever L will engage the first projection G on the tray and move the same until the first set or four of the cans are beneath the cappingirons. During this movement the rotation of the cam Y on the shaft E lowers the rod X and the lever U with the central tube and capping-irons, so that when the cans are beneath the irons the weighted tip-rods A rest upon the caps, holding them in place. The brushes X X, which during this portion of the rotation of the shaft E were in line with the tops of the caps and brushed the same, are now raised by the depression of the ends of the levers Y, which are connected with the central tube S, so as to be clear of the said caps. The rotation of the shaft E with the cam R causes a step-bystep rotation of the shaft T, so that the wire solder is fed to the heated capping-irons,which are rotated, owing to their pinions and the movement of the rack mechanism caused by the lever D, having its lower end moving in the groove portionof the periphery of the wheel F, so that the melted solder is carried so as to enter all portions of the groove on the top of the can and in which the edges of the cap are seated. A further rotation 'of the shaft E and the cams still further raises the capping-irons, so that they are clear of the cans,when the lower end of the pivoted lever L riding on the cam portion M of the wheel F, opens the valve K whereby a cold blast is directed on the hot melted solder, solidifying and cooling the same. A further rotation of the shaft raises the irons, and with them the tip-rods, so that the latterare freed from the cans and the said cans are free to be moved. As the shaft further rotates, the valve K is closed and the tube S, with the irons, lowered for anotheroperation. The le vers K and L are also moved in such position that the lever K engages the first projection on the tray, and as it moves draws the same until the second set of cans is beneath the capping irons, when the operation of the parts is similar to that already described. The next movement of the levers engages the same lever K with the second projection G, moving the tray until the third set of cans is beneath the irons, the operation of the parts then being as before described. A further movement of the levers'engages the lever L with the first projection of the second tray and draws the same underneath the can, the lever L, however, during a portion of the movement engaging the third projec tion of the first tray and drawing the same so as to prevent a bumping or jarring action of the trays.

To render the acid-feed intermittent in its action and prevent its operation when the cans are not on the trays,l construct the rod 1 of right and left screw-thread sections having a connecting collar F, with an arm G adapted to contact with a can and move said collar, so as to shorten the rod. A spring J fastened to the arm G3 and frame, serves to restore the arm G to its normal position when no can is in the way, therebylengthening the rod F so that the plunger-head D will not raise the acid to the overflow B Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
